In response to the demand for air conditioning in residential places, office places and public places, the utilization rate of air conditioners is also gradually increasing. The air conditioner currently widely used is a compressor refrigeration air conditioner. The working principle of this air conditioner is: the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gas, and sends it to the condenser for cooling. After cooling, it becomes a medium-temperature and high-pressure liquid refrigerant and enters the drying bottle for filtration and dehumidification. The medium-temperature liquid refrigerant is throttled and reduced in pressure by the expansion valve to form a low-temperature and low-pressure gas-liquid mixture. It absorbs heat in the air through the evaporator and vaporizes into a gas, and then returns to the compressor to continue compression and refrigeration cycle.

[0003] Based on the working principle of existing compressor refrigeration air conditioners, a compressor must be used. Such usage will easily cause the following problems:

[0004] 1. The power consumption of the compressor is high, which causes the annual power supply demand to increase rapidly;

[0005] 2. The assembly and use of the compressor, air conditioner and pipeline will take up more space, and the compressor will generate a lot of noise when running;

[0006] 3. When the compressor is running, it will generate high-temperature hot air and discharge it to the outside, causing the outdoor temperature to rise abnormally;

[0007] Based on the working principle and existing problems of the above-mentioned compressor refrigeration air-conditioning, if it is installed and configured in outdoor public places such as bus stops, it is necessary to increase energy consumption to achieve high-power refrigeration or configure multiple air conditioners to create a cool environment in hot outdoor places. The cost of use is extremely high and the area occupied is large. Secondly, the hot air and noise emissions of the compressor can easily cause discomfort to passers-by. The actual application performance of the compressor refrigeration air-conditioning in outdoor places is not good. Therefore, there is an urgent need for a cooling device that can be used in outdoor places, has good refrigeration effect, occupies a small area, and does not require excessive cost.

[0030] The technical solutions in the embodiments of the present utility model will be described below in conjunction with the accompanying drawings. Example 1

[0031] like Figure 1 , Figure 2 and Figure 6As shown, an energy-saving and cooling device for outdoor use without a compressor includes a bracket 1, an upper box body 2 is provided on the top of the bracket 1, a lower box body 3 is provided on the bottom of the bracket 1, fans 4 are respectively provided at the openings of the upper box body 2 and the lower box body 3, the upper box body 2 and the lower box body 3 are interconnected through an aluminum heat exchange tube 5, a plurality of aluminum heat exchange tubes 5 are provided and arranged in parallel, a plurality of grooves 6 are arranged on the outer surface of the aluminum heat exchange tube 5, a front guard plate 7, a rear guard plate 8, a left guard plate 9, and a right guard plate 10 are respectively detachably arranged on the four peripheral edges of the bracket 1, the front guard plate 7, the rear guard plate 8, the left guard plate 9, the right guard plate 10 and the bracket 1 together form a guide channel 11, the left guard plate 9 is provided with a water inlet 12, the right guard plate 10 is provided with a water outlet 13, and the height of the water inlet 12 is greater than the height of the water outlet 13.

[0032] In this embodiment, the device realizes the cooling function based on the phase change mechanism of the working fluid. A circulating water pipeline is connected at the water inlet 12 and the water outlet 13, so that flowing cooling water is passed into the guide channel 11. Since the height of the water inlet 12 is greater than the height of the water outlet 13, the cooling water is sprayed to the upper part of the aluminum heat exchange tube 5, and then flows downward on the surface of the aluminum heat exchange tube 5 due to gravity, and then discharged from the water outlet 13. At the same time, the fan 4 is used to guide the hot air from the outside to enter from one end of the aluminum heat exchange tube 5, and the hot air flowing in the aluminum heat exchange tube 5 exchanges heat with the water mist on the surface of the aluminum heat exchange tube 5 to obtain cold air, and then the cold air is blown out from the other end of the aluminum heat exchange tube 5 through the fan 4, so as to form comfortable dry cold wind.

[0033] It should be noted that the plurality of grooves 6 can increase the contact area between the aluminum heat exchange tube 5 and the cooling water, thereby enhancing the heat exchange performance of the aluminum heat exchange tube 5 .

[0034] It should be noted that since the upper box body 2 and the lower box body 3 are respectively erected at the upper and lower positions of the bracket 1, the front guard plate 7, the rear guard plate 8, the left guard plate 9, and the right guard plate 10 are all detachably mounted on the bracket 1. Therefore, the device can be easily installed on the billboard of the bus stop to achieve assembly and configuration with the bus stop. It is also easy to disassemble and maintain to ensure its service life.

[0035] It should be understood that the device does not require a compressor and a refrigerant during the entire cooling process. The same cold air cooling function can be achieved by using only the electrical energy of the fan 4. Compared with the existing compressor refrigeration and air conditioning, the device can save a lot of energy consumption costs and use costs. At the same time, it will not cause discomfort to passers-by due to the hot air and noise emissions from the compressor. The device has a simple and light structure and low use cost. It can not only reduce the occupied area of ​​outdoor public places, but also is easy and quick to assemble, and easy to disassemble and maintain. It is suitable for outdoor public places such as bus stops and building halls.

[0036] It should be understood that the cooling and cooling of this device is actually related to the ambient temperature and humidity. Please refer to Figure 7 When the device is applied in the actual field, under the environmental condition of less than or equal to 75% humidity, the higher the temperature of the closed space, the greater the temperature difference before and after cooling, and the more obvious the cooling effect achieved by the device.

[0037] The fans 4 are provided in plurality and are equidistantly arranged at the openings of the upper box body 2 and the lower box body 3. The fans 4 are provided in plurality at the upper box body 2 and the lower box body 3, which can facilitate the collection of hot air from the outside and enter the interior of the aluminum heat exchange tube 5, and discharge cold air after heat exchange, and also facilitate the diffusion of cold air to the surroundings, thereby enhancing the cooling effect.

[0038] The openings of the upper box body 2 and the lower box body 3 are covered with a filter 14, and the fan 4 is located inside the filter 14. The filter 14 can prevent foreign debris from being drawn into the fan 4 or the aluminum heat exchange tube 5, prevent the fan 4 from being damaged by debris, and prevent the aluminum heat exchange tube 5 from being blocked or damaged by water.

[0039] The inner diameter of the aluminum heat exchange tube 5 is set to 10-28 mm. The inner diameter of the aluminum heat exchange tube 5 is controlled to 10-28 mm to achieve the best air heat exchange effect.

[0040] The joints of the upper box body 2, the lower box body 3 and the aluminum heat exchange tube 5 are provided with waterproof glue 15. The waterproof glue 15 can prevent the cooling water flowing in the guide channel 11 from leaking out from the joints of the upper box body 2, the lower box body 3 and the aluminum heat exchange tube 5, and prevent the mist of the cooling water from being discharged outward.

[0041] The plurality of grooves 6 are arranged in a threaded shape around the outer surface of the aluminum heat exchange tube 5 and extend along the axial direction of the aluminum heat exchange tube 5. The inner wall of the aluminum heat exchange tube 5 is set to a smooth surface. The distribution design of the threaded grooves 6 can further increase the contact area between the aluminum heat exchange tube 5 and the cooling water, and under the guidance of the threaded grooves 6, the cooling water flows around the surface of the aluminum heat exchange tube 5, thereby enhancing the heat exchange effect and improving the cooling efficiency. Example 2
